Horticulture is a priority sector in many states of India as it has potential to improving the socio economic condition of the farmers. Gujarat state is the fourth leading state in fruit production with 9% share at the national level. This study is conducted to correlate major weather parameters with the production of major fruit crops of Navsari district in Southern Gujarat. The study reveals that production and productivity of 4 major fruits (banana, mango, sapota and papaya) has moderate negative correlation with mean annual temperature (MAT) i.e > -50% except the productivity of land under banana. Whereas, it showed very weak negative and non significant relation with total annual Rainfall (TAR). Correlation of all four fruit production ranged between -34 to -53% and -0.7 to -62% for productivity with both MAT and TAR, respectively.
Neem (Azadirachta indica A. Juss.) is an important woody angiosperm belonging to the order Rutales, family Meliaceae. Neem is a botanical relative of mahogany and is native to India and Burma.The studies on genetic improvement of Neem are not well documented so for the effective use of Neem resources, effective exploration and improvement required. The current paper aimed to review all the studies related to genetic improvement of neem to understand genetic variability in Neem and its improvement can be done in this medicinally important tree species. In thispaper various studies has been reviewed that provided status of the improvement work on Neem all over the world. Tree breeders assessed the genetic resources available for improvement, selecting genes with high utility and economic value and packaging them into genotypes that may be utilized to start commercial plantations. Researchers used biotechnological, traditional tools to improve this species. Despite its widespread ranged studies and numerous researches for better understanding breeding efforts must be expanded.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
